I’ve always been fascinated by Grantham House, the Crawleys’ London residence. When they went to the city for the “season”, this was where they would stay. There’s actually a list of the (known) rooms, including the intriguing “Octagonal Drawing Room.” In DA-land, the house was built in 1849, during the height of the massive Victorian building projects in London. Lady Violet was 7 years old at the time! 🙂 https://downtonabbey.fandom.com/wiki/Grantham_House
